Název v původním jazyce

The role of root system in the dieback of silver birch (Betula pendula Roth.) in the air-polluted region Krušné hory Mts.

Popis výsledku v původním jazyce

120 root systems and trunks of the 20-year old birch trees and 60 root systems and trunks of the 15-year old birch trees affected by defoliation and with no visual symptoms of damage were analyzed in the air-polluted region of Krušné hory Mts. In the given region, birch develops a superficial or anchoring root system of the circular shape. A greater effect of defoliation was recorded in trees with the superficial root system. The defoliation was in correlation with the extent of bole rot, root system rot and rooting depth. The share of root system branches infested by rot increased with the increasing defoliation. Dominating fungi on roots were Armillaria gallica and Armillaria ostoyae. The degree of defoliation was directly proportional to the extentof bole rots induced by Trametes confragosa and Armillaria gallica, infecting frost ribs in the trunks.
